GUARD FOR HEEL-SCOUBING MACHINES.

Application filed September 18, 1923. Serial No. 663,511.

This invention relates to improvements in machines used in the manufacture of shoes, and more particularly to a guard intended for use in connection with a heel scouring machine which comprises an abrading wheel having a peripheral abrading surface.

The principal ObjGCQ-Of the invention is to provide a guard and support therefor, the entire device being of extremely simple construction and readily applicable to a scouring machine. I

A further object of the invention is to provide a device of this character which may be used in connection with abrading wheels of different diameters, the guard being adjustable toward and from the axis of the wheel so that it may be positioned close to the peripheries of wheels of various sizes. Another object is to afford a construction which permits the guard to be adjusted in a plane paralleling the wheel axis so that heels of different heights may be finished.

Other objects, which are more closely related to the details of construction of a preferred embodiment of the invention will become apparent as the description proceeds in connection with the accompanying drawings, wherein such an embodiment is disclosed.

In the drawings Fig. 1 is a side elevational view,

Fig. 2 is an end elevational view looking to the right in Fig. 1, and

Fig. 3 is a sectional detail on the line 3-3 of Fig. 1 looking in the direction of the arrows.

Referring to the drawings for a more detailed description, indicates, conventionally, a bearing for a mandrel 11 which extends therethrough and has fixedly positioned upon its free end an abrading wheel 12 having a peripheral abrading surface 13.

Ordinarily, in presenting the heel of a shoe or a piece of heel stock, before application to a shoe, to the abrading surface the same is held in position by the operator, as indicated in dotted lines in Fig. 1. In order to prevent the abrading surface from mutilating the vamp of the shoe, or from engaging a portion of the stock which is not to be finished, the operator positions adjacent the wheel some rigid abutment, upon which the shoe or stock may be rested. The present invention comprises a substantially rigid abutment which, preferably, is in the form of a rod 14 substantially arcuate, as indicated clearly in Fig. 2, and

adapted to extend over a portion of the periphery of the wheel. The rod is substantially V-shaped in cross section to permit of ready movement of the heel as the base of the heel bears against the abutment and during its presentation to the wheel. As a mounting for this abutment member or rod it is desirable to provide a construction which permits the rod to be adjusted longitudinally of the wheel axis so that the abutment member may be moved toward and from the margin of the wheel. Heels of different shoes vary in height, and itis important that the vamp of the shoe be maintained, at all times. away from the abrading surface. Again, the supporting device should permit the abutment member 14 to be moved toward and from the axis so that the attachment may be used in connection with wheels of different diameters, and when used with all wheels be positioned substantially close to the abrading surface, as indicated in Fig. 2. i

Such a support is shown in the drawings and comprises a bearing clamp formed of two clamping halves 15, 16 surrounding the bearing 10 and held thereon by means of bolts 17 securing the two halves together. The clamp portion has an outwardly extending arm 18, provided with lugs 19, 20; and an arm 21, the outer end of which is forked, as at 22. The forked portion 22 carries a screw 23 which clamps upon the arm a substantially L-shaped bracket 24. The bracket 24 is p-ivotally movable about the clamping screw 23 and has therein a slot 24 permitting the bracket to be moved rectilinearly as well as pivotally. Through the outer end of the bracket extends a guide rod 25 corresponding to a guide rod 26 extending through openings in the lugs 19, 20 upon the arm 18. These rods, together, project through openings in the free ends of the abutment member 14 and support the latter adjacent the wheels. Collars 28 carrying set screws 29 are positioned upon the guide rods and maintain the latter in set position, it being understood that the rods may be adjusted in the lugs 19, 20 and in the bracket 24 to move the abutment member toward and from the margin of the wheel. By this adjustment the guard may be positioned with respect to the margin of the wheel in accordance with the height of the heels to be finished.

In order to adapt the guard to Wheels of difierent diameters the bracket 24 may be pivotally moved about the clamping screw and also, if desired, moved rectilinearly on the arm 21, the slot 24 in the bracket permitting this latter adjustment. By moving the bracket in this manner, and, at the same time, pivoting the same about the clamping screw 23 as an axis, the abutment member 14 may be adjusted toward and from the wheel axis, to conform to wheels of difierent diameter, as shown in dotted lines in Fig. 2.

It should be understood that the invention is not limited to the particular type of abutment member disclosed, or to the details of the support therefor. The gistof the invention is an abutment member adapted to extend over a portion of the periphery of a scouring wheel and held rigidly in position by a support, which pen mits the same to be adjusted longitudinally of the wheel axis for the purpose of conforming to the height of the heel to be finished and toward and from the wheel axis to permit the abutment rod to be positioned adjacent the peripheries of wheels of different diameters. It should be noted that the adjustment of the device longitudinally of the axis maybe efi'ected without disturbing the adjustment of the bracket 2st, which is moved only when the abutment member is to be moved at an angle to the axis of the wheel to carry the same closer to or farther from the axis.

I claim: H

l. A guard attachment for an abrading wheel comprising an abutment member adapted to extend over a part of the periphery of said wheel and at least two spaced supports for securely maintaining said member in operative position, said member being pivotally connected at one end to one support so that it may swing toward and from said periphery and so connected to the other support as to permit it to so swing while being still maintained by both supports against movement axially oi the abrading wheel.

2. An attachment such as defined in claim my hand. I
